android-satellite-menu實現點擊主按鈕，會彈出多個圍繞著主按鈕排列的子按鈕，從而形成一個衛星彈出式菜單。子按鈕彈出和消失的動畫效果都很棒。這種彈出式菜單按鈕應用在Path2.0中。

用法

在你的view xml中添加組件定義，如下示例：

xmlns:android="http://schemas.android.com/apk/res/android"

xmlns:sat="http://schemas.android.com/apk/res/android.view.ext"

android:layout_width="fill_parent"

android:layout_height="fill_parent"

android:orientation="vertical" >

android:id="@+id/menu"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_gravity="bottom|left"

android:layout_margin="8dp"

sat:satelliteDistance="170dp"

sat:mainImage="@drawable/ic_launcher"

sat:totalSpacingDegree="90"

sat:closeOnClick="true"

sat:expandDuration="500"/>

屬性有：

satelliteDistance ?The distance of items from the center button

totalSpacingDegree ?The degree between the first and the last item.

closeOnClick ?Defines if the menu shall collapse after clicking on a menu item.

expandDuration ?The duration of expand and collapse operations in milliseconds.

當在你的View XML定義之后，可按以下代碼添加子菜單：SatelliteMenu menu = (SatelliteMenu) findViewById(R.id.menu);

List items = new ArrayList();

items.add(new SatelliteMenuItem(4, R.drawable.ic_1));

items.add(new SatelliteMenuItem(4, R.drawable.ic_3));

items.add(new SatelliteMenuItem(4, R.drawable.ic_4));

items.add(new SatelliteMenuItem(3, R.drawable.ic_5));

items.add(new SatelliteMenuItem(2, R.drawable.ic_6));

items.add(new SatelliteMenuItem(1, R.drawable.ic_2));

Each menu item takes the ID of the item and the drawable resource for the item.

In order to listen clicks on items:

menu.setOnItemClickedListener(new SateliteClickedListener() {

public void eventOccured(int id) {

Log.i("sat", "Clicked on " + id);

}

});
